组元多样性是改善Fe基非晶纳米晶合金非晶形成能力和软磁性能的重要方式之一,基于Nanomet合金,通过Fe基二元相图设计成分,利用单辊甩带法制备出Fe80(AlxSiy)2.4B12.6P4Cu1(x/y=0,1/5,1/2,1/1,2/1)合金,探讨了 x/y变化对合金非晶形成能力、热稳定性与软磁性能的影响,研究表明,x/y比例的提高能够增强合金的初晶相晶化温度与非晶形成能力,当x/y=1时,Fe80(Al1Si1)2.4B12.6P4Cu1合金的非晶形成能力较高,退火温度窗口拓宽,在500 ℃退火1 min后表现出优异的软磁性能,其中矫顽力为1.27 A/m,磁导率达17551,由于Fe含量并没有变化,Al的掺杂对合金的饱和磁感应强度影响较小.
The effect of Al doping on the preparation and soft magnetic properties of Fe based amorphous nanocrystalline alloys
Component diversity is one of the important ways to improve the amorphous formation ability and soft magnetic properties of Fe based amorphous nanocrystalline alloys.Based on Nanomet alloy,this paper designs the composition through Fe based binary phase diagram and uses single roll strip casting method to prepare Fe80(AlxSiy)2.4B12.6P4Cu1(x/y=0,1/5,1/2,1/1,2/1)alloy.The influence of x/y changes on the amorphous for-mation ability,thermal stability,and soft magnetic properties of the alloy is explored.The research shows that the increase of x/y ratio can enhance the initial crystallization temperature and amorphous formation ability of the alloy.When x/y=1,the amorphous formation ability of Fe80(AlxSiy)2.4B12.6P4Cu1(x/y=0,1/5,1/2,1/1,2/1)alloy is higher,and the annealing temperature window is widened.After annealing at 500 ℃ for 1 min,it exhibits excellent soft magnetic properties,with coercivity of 1.27 A/m and magnetic permeability of 17551.Due to the Fe content remains unchanged,the doping of Al has a minor impact on the saturation magnet-ic induction of the alloy.
